# Glossary

Central reservation
Strip of land or barrier separating a dual carriageway
Directionality
Whether a road is one-way, two-way or no-entrance (unknown)
Divided highway
See dual carriageway
Dual carriageway
A road or highway in which the two directions of traffic are separated by a central barrier or strip of land, known as a central reservation or median
Freeway
Geometry
The layout or shape of a road segment. Each road is made up of straight line segments. These can be arbitrarily short, effectively allowing curves
Geometry node
See Node
The level or elevation of a road with respect to surrounding roads. So a road would normally be at level grade. A road going underneath in a tunnel would be a -1 grade. A road going over would be a +1 grade. At complicated junctions such as freeway interchanges there can be many levels. So on a flat map we assign levels to show that while the roads cross, they do not connect because they are at different heights or elevations.
HOV
High Occupancy Vehicle. A vehicle with 2 or more occupants. HOV Lanes, also known as Carpool Lanes and Transit Lanes, are lanes restricted for the use of cars carrying a specified number of occupants
Junction
The point where two or more road segments connect; often incorrectly referred to as a 'node'.

Junctions look differently depending on the situation:

• Selected and editable segment junction
• Selected and uneditable segment junction (no permissions to change)
• Changed, unsaved junction
Map tile, tile
The Waze map is divided into a grid using 1KM square areas which are called tiles or map tiles. Changes to map are processed on a per-tile basis. Changes to any part of a map tile causes Waze to mark the tile as changed and it will be rebuilt in the next map update cycle.
Median, median barrier
Strip of land or barrier separating a divided highway or motorway
Motorway
Munching
Node
When editing a segment or landmark, large black squares appear where the segment changes direction from straight. Click and drag them individually to alter the geometry of the segment or or landmark. Click and drag the white circles on a segment to add them to an object or press the d key while the mouse is hovered over them to delete the node.
Origin
Starting point for a driving route
Unconfirmed roads marked with dots (cookies). Roads that have not been driven on since created or significantly edited in Cartouche. Driving over these roads earns you points and turns your car icon into a Pacman-type character that "munches the dots"
Pathfinder
The road segments linking roadways that are not necessarily their own named streets. They are often part of the rampways getting on or off freeways and highways or between freeways. After initially exiting a freeway they help further direct drivers through additional turn decisions before reaching the desired roadway or street. See the Junction Style Guide for more information.
Pothole
Also called a kettle or chuckhole, is a type of disruption in the surface of a roadway where a portion of the road material has broken away, leaving a hole.
Ramp
A freeway entrance or exit; sliproad. Ramps may be on-ramps or off-ramps. Ramps used to connect roads at a different grade from the connecting road or freeway. See the Map Legend and the Junction Style Guide for more detail.
